Import Real-Time Cvent Data in ColdFusion to Build Applications

Adobe ColdFusion is a web and mobile application development platform. It uses its own scripting language, ColdFusion Markup Language (CFML), to create data-driven websites as well as generate remote services, such as REST.

When ColdFusion is paired with the CData JDBC Driver for Cvent, you can link your ColdFusion web and mobile applications to operational Cvent data. This allows for your applications to be more robust and complete. This article details how to use the JDBC driver to create a table populated with Cvent data from within a ColdFusion markup file.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Cvent data. When you issue complex SQL queries to Cvent, the driver pushes supported SQL operations, like filters and aggregations, directly to Cvent and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Cvent data using native data types.

Configuring the Connection to Cvent

You will need a JDBC connection string to establish a connection between Coldfusion and Cvent.

Before you can authenticate to Cvent, you must create a workspace and an OAuth application.

Creating a Workspace

To create a workspace:

1. Sign into Cvent and navigate to App Switcher (the blue button in the upper right corner of the page) >> Admin.
2. In the Admin menu, navigate to Integrations >> REST API.
3. A new tab launches for Developer Management. Click on Manage API Access in the new tab.
4. Create a Workspace and name it. Select the scopes you would like your developers to have access to. Scopes control what data domains the developer can access.
   • Choose All to allow developers to choose any scope, and any future scopes added to the REST API.
   • Choose Custom to limit the scopes developers can choose for their OAuth apps to selected scopes. To access all tables exposed by the driver, you need to set the following scopes:

     event/attendees:read	event/attendees:write	event/contacts:read
     event/contacts:write	event/custom-fields:read	event/custom-fields:write
     event/events:read	event/events:write	event/sessions:delete
     event/sessions:read	event/sessions:write	event/speakers:delete
     event/speakers:read	event/speakers:write	budget/budget-items:read
     budget/budget-items:write	exhibitor/exhibitors:read	exhibitor/exhibitors:write
     survey/surveys:read	survey/surveys:write

Creating an OAuth Application

After you have set up a Workspace and invited them, developers can sign up and create a custom OAuth app. See the Creating a Custom OAuth Application section in the Help documentation for more information.

Connecting to Cvent

After creating an OAuth application, set the following connection properties to connect to Cvent:

• InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
• OAuthClientId: The Client ID associated with the OAuth application. You can find this on the Applications page in the Cvent Developer Portal.
• OAuthClientSecret: The Client secret associated with the OAuth application. You can find this on the Applications page in the Cvent Developer Portal.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Cvent JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

Adding a Data Source and Creating a Table

After configuring the connection, follow the steps below to add the CData JDBC Driver to ColdFusion's lib directory, add a new data source, test the connection, create a ColdFusion markup file, and, finally, make a real-time connection with Cvent data and display it in a table written in the ColdFusion Markup Language, or CFML:

1. Copy the JDBC Driver for Cvent and lic file from "C:\Program Files\CData[product_name]\lib" to "C:\ColdFusion2021\cfusion\wwwroot\WEB-INF\lib". cdata.jdbc.cvent.jar cdata.jdbc.cvent.lic

   Note: If you do not copy the .lic file with the jar, you will see a licensing error that indicates you do not have a valid license installed. This is true for both the trial and full versions.

2. From the ColdFusion administrator interface, choose Data & Services.
3. Here, we can "Add New Data Source". The data source name can be any name, provided it conforms to the ColdFusion variable naming conventions. For our JDBC driver, choose "other", then click the "Add" button.
4. Next, populate the driver properties.
   • JDBC URL will need to be in the format: jdbc:cvent:|connectionString|.
   • A typical connection string looks like this:

     jdbc:cvent:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;InitiateOAuth=GETANDREFRESH

   • The Driver Class is: cdata.jdbc.cvent.CventDriver
   • The Driver Name is arbitrary and simply used to recognize the data source in the ColdFusion administration console.
5. Now, test the connection by clicking the check mark to the left of the CDataCventJDBC data source you just created. When the data source reports an "OK" status, it is ready for use.
6. Next, create a new ColdFusion Markup file (.cfm) and place it in the wwwroot directory ("C:\ColdFusion2021\cfusion\wwwroot") for ColdFusion.

   The following code queries the data source:

               
           <cfquery name="CventQuery" dataSource="CDataCventJDBC"> 
             SELECT * FROM Events 
           </cfquery> 
       

   And a CFTable can be used to quickly output the table in HTML:

               
             <cftable  
             query = "CventQuery" 
             border = "1" 
             colHeaders 
             colSpacing = "2" 
             headerLines = "2" 
             HTMLTable 
             maxRows = "500" 
             startRow = "1"> 
   
             <cfcol header="<b>Id</b>" align="Left" width=2 text="Id"/> 
   
             <cfcol header="<b>Title</b>" align="Left" width=15 text="Title"/> 
   
             ...
   
           </cftable> 
       

   Full code, including the HTML portion is available below:

               
           <html> 
           <head><title>CData Software | Cvent Events Table Demo </title></head> 
           <body> 
           <cfoutput>#ucase("Cvent Events Table Demo")#</cfoutput> 
           <cfquery name="CventQuery" dataSource="CDataCventJDBC"> 
   
             SELECT * FROM Events 
   
           </cfquery> 
           <cftable  
             query = "CventQuery" 
             border = "1" 
             colHeaders 
             colSpacing = "2" 
             headerLines = "2" 
             HTMLTable 
             maxRows = "500" 
             startRow = "1"> 
             <cfcol header="<b>Id</b>" align="Left" width=2 text="Id"/> 
   
             <cfcol header="<b>Title</b>" align="Left" width=15 text="Title"/> 
   
             ...
   
           </cftable> 
           </body> 
   
           </html>  
       

7. Finally, run the code locally in a browser at the default port of 8500. It produces a table populated with Cvent data!

As a note, the CData JDBC Drivers also support parameterized queries using the cfqueryparam element. For example: SELECT * FROM Account WHERE name =
